摘　　要：采空区积水是影响煤矿安全生产的主要水患。能否准确估算采空区积水量,有目的、有计划对采空区积水进行疏放是治理水患的关键。以煤峪口矿410盘区51020巷为研究对象,通过在排水过程中利用测定探放水孔水压,计算水位,综合分析水力连通情况,反算充水系数,圈定积水范围,确定积水标高,准确地计算出采空区积水量,为探放水工作提供了可靠的技术依据。Water accumulation in the mining area is a major water hazard that affects the safety production of coal mines.Whether the amount of water in the mining area can be accurately estimated and the water in the mining area can be purposely and systematically released is the key to control the flooding.Taking 51020 roadway in 410 area of Meiyukou Mine as the object of study,the amount of water accumulation in the mining area was accurately calculated by measuring the water pressure of water exploration and release holes,calculating the water level,comprehensively analyzing the hydraulic connection,back-calculating the water filling coefficient,circling the water accumulation range and determining the water accumulation elevation in the drainage process,which provided a reliable technical basis for water exploration and release work.
